The environmental condition detec-tor (6-i) is for providing an early warning of the presence of an environmental condition (smoke or carbon monoxide gas, etc.) to persons in remote areas of a build-ing. The detector (6-1) sensing the envi-ronmental condition emits an audible tonal pattern alarm (fig. 3-7), while transmit-ting a radio signal directly to other envi-ronmental condition detectors (6-2 to 6-n) to activate their alarms and to activate an electronically stored human voice record-ing (or synthesized voice) that indicates the location of the environmental condition detector sensing the environmental condi-tion, or the type of environmental condi-tion, or both. Rechargeable light modules (130, 140, 150) separate from the detector are included that receive the signal from the detector (170, 180) and illuminate areas and paths of egress for the duration of the alarm condition or in case of power failure (160).

La présente invention concerne un détecteur d'anomalie des conditions ambiantes (6-1) qui est destiné à prévenir rapidement des personnes qui se trouvent dans des zones éloignées d'un bâtiment en cas d'incident (fumée, monoxyde de carbone, etc.). Le détecteur (6-1) qui capte des conditions ambiantes anormales déclenche une alarme sonore (fig. 3-7) et commande par radiosignal aux autres détecteurs de conditions ambiantes anormales (6-2 à 6-n) de déclencher leurs alarmes respectives et de diffuser un enregistrement de voix humaine (ou voix de synthèse) sur support électronique qui indique l'emplacement du détecteur qui a détecté l'anomalie, ou le type d'anomalie, ou les deux. Des modules lumineux rechargeables (130, 140, 150) distincts du détecteur qui a détecté l'anomalie, reçoivent le signal transmis par le détecteur (170, 180) et éclairent les zones et voies de sortie pendant la durée de l'alerte ou en cas de panne de courant (160).
